Air Bag Diagnostic Module: Service and Repair
REMOVAL
WARNING:
-
TO AVOID ACCIDENTAL DEPLOYMENT AND POSSIBLE PERSONAL INJURY, THE BACKUP POWER SUPPLY MUST BE
DEPLETED BEFORE REPAIRING OR REPLACING ANY FRONT OR SIDE AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM
(SRS) COMPONENTS AND BEFORE SERVICING, REPLACING, ADJUSTING OR STRIKING COMPONENTS NEAR THE
FRONT OR SIDE AIR BAG SENSORS, SUCH AS DOORS, INSTRUMENT PANEL, CONSOLE, DOOR LATCHES, STRIKERS,
SEATS AND HOOD LATCHES.
-
THE SIDE AIR BAG SENSORS ARE LOCATED AT OR NEAR THE BASE OF THE B-PILLAR.
-
TO DEPLETE THE BACKUP POWER SUPPLY ENERGY, DISCONNECT THE BATTERY GROUND CABLE AND WAIT AT
LEAST ONE MINUTE. BE SURE TO DISCONNECT AUXILIARY BATTERIES AND POWER SUPPLIES (IF EQUIPPED).
-
THE AIR BAG ELECTRONIC CRASH SENSOR (ECS) ORIENTATION IS CRITICAL FOR CORRECT SYSTEM OPERATION. IF
A VEHICLE EQUIPPED WITH AN AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) HAS BEEN INVOLVED IN A
COLLISION IN WHICH THE CENTER TUNNEL AREA HAS BEEN DAMAGED, INSPECT THE MOUNTING AND BRACKET
FOR DEFORMATION. IF DAMAGED, THE ECS MUST BE REPLACED WHETHER OR NOT THE AIR BAGS HAVE DEPLOYED.
IN ADDITION, MAKE SURE THE AREA OF THE ECS MOUNTING IS RESTORED TO ITS ORIGINAL CONDITION.
CAUTION: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage can result.
NOTE: Repair is made by installing a new part only. If the new part does not correct the condition, install the original part and perform the diagnostic
procedure again.
1. Disconnect the battery ground cable and wait at least one minute.
2. If equipped with a full floor console panel, remove the floor console panel.
3. Pull back the floor carpet from underneath the instrument panel at the center tunnel and position out of the way.
6. Remove the ECS module.
INSTALLATION
WARNING: THE TIGHTENING TORQUE OF THE AIR BAG ELECTRONIC CRASH SENSOR (ECS) MODULE RETAINING NUTS IS
CRITICAL FOR PROPER SYSTEM OPERATION.
NOTE:
-
Repair is made by installing a new part only. If the new part does not correct the condition, install the original part and perform the diagnostic
procedure again.
-
Make sure to tighten the retaining nuts to specification.
-
When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the Powertrain Control Module
(PCM) relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.
1. Follow the removal procedure in reverse order.
2. Prove out the air bag system.
